or logistical reasons, I measured one of the 801 D4 Signature speakers, serial number 2320 0004094 FP 44229, in Tom Fine’s listening room rather than at my home. (My thanks to Tom and Mike Barney for moving furniture to allow me sufficient room for the measurements with the loudspeaker away from the walls and firing along a room diagonal.) I used DRA Labs’ MLSSA system with a calibrated DPA 4006 microphone to measure the speaker’s behavior in the farfield and an Earthworks QTC-40 mike for the nearfield responses. Because of the speaker’s weight—almost 222lb—it wasn’t possible to raise it off the floor. I therefore performed all the farfield measurements at a 1m
